Filed: 1996-08-16
Abstract: There is disclosed a method of playing back information from an optical multilayer disk having a plurality of recording disks stacked on top of each other, by the use of an optical pickup device. In order to switch the focused recording layer from a first one to a second one so that data is read from the second recording layer, the focus balanced condition of the pickup device is switched from a setting providing a focus error characteristic adapted for the first recording layer to a reference setting providing a neutral focus error characteristic. Then, the focal point of the pickup device is moved from the first recording layer. Subsequently, the pickup device is focused onto the second recording layer, and data is read from the second recording layer. Thereafter, the focus balanced condition of the pickup device is switched to a setting adapted to the second recording layer.

Abstract: A sectional structure is provided herein. Such structure includes a glazier's strip section having a first side brace flange for bracing one side of a glass pane.  Such structure further includes a casing section having a second side brace flange for bracing the other side of the glass pane. Such structure further includes a bottom rest which is positioned at substantially a right angle with respect to the second side brace flange, the glass pane being disposed in a space which is defined by the first side brace flange, the second side brace flange and the bottom rest. The glazier's strip section and the casing section are formed mutually interlockable. They have fixing means for detachably attaching the glazier's strip section to the casing section. The fixing means includes a first locking claw which is formed on the casing section, and a second locking claw which is formed on the glazier's strip section for interlocking with the first locking claw. Such structure further includes a first brace member, which is formed on the casing section, and a second brace member, which is formed on the glazier's strip section. The second brace member braces against the first brace member which forms a pivot between the glazier's strip section and the casing section. In this manner the glazier's strip section is pivotable between a locked position and an unlocked position, with the first brace member and the second brace member being urged against each other. The glazier's strip section is configured to be turnable around a pivot which is constituted by cooperation of the first brace member and the second brace member. This cooperation serves to press the first side brace flange against a surface of the glass pane into the locked position. Furthermore, by such action, the first locking claws and the second locking claws become interlocked.

Title: Method and apparatus for measuring and controlling the surface characteristics of sheet materials such as paper
Inventor: GOSS JOHN D
IPC: G01N21/47
Filed: 1996-05-02
Abstract: An on-line laser triangulation position sensing system provides measurements of the surface features of a moving sheet such as paper. The measurements are correlatable with measurements made with standard laboratory surface smoothness testers and provide predictions of the printability of paper during its fabrication. The sensing system includes a segmented balance detector having a high frequency response. The sensing system further includes signal processing circuitry comprising a plurality of channels, each channel including a filter. The various filters have different cutoff frequencies for passing different frequency spectra representing ranges of surface feature scale sizes. The cutoff frequency of each filter is varied in response to variations in sheet speed. The sheet sensing system further includes a sheet stabilizer to minimize flutter in the measurement region and a standardizing member permitting performance verification of the sensor system at at least one scale size spectrum. The sensing system may also be provided with a sheet compressor to compress the sheet in the measurement region so as to simulate the pressures applied to sheet samples by laboratory air leak smoothness testers. The output of the position sensing system may be used in conjunction with various kinds of papermaking machines to control one or more of the many papermaking process parameters that determine the smoothness or texture of the final product. The sensing system can be used to measure tissue crepe and such measurement can be utilized to control various crepe-determining stages in a tissue making machine and to monitor the condition of the creping or doctor blade in such a machine.

Title: Subcritical process for drying sol-gel derived porous bodies
Inventor: KIRKBIR FIKRET
IPC: C03B8/02
Filed: 1995-08-17
Abstract: A process is disclosed for drying sol-gel derived porous wet bodies without inducing cracks therein. The wet gel preferably is immersed in a liquid solvent before being placed inside a drying chamber capable of withstanding relatively high pressures and temperatures. After the wet gel is loaded, the chamber is sealed from the outside environment, and then is heated from outside the chamber in a controlled manner until a prescribed subcritical pressure is reached. The final temperature and pressure are always lower than the critical temperature and pressure of the drying solvent. The solvent vapor is then evacuated from the chamber in a controlled fashion to decrease the pressure until ambient pressure is reached, while preferably maintaining the temperature inside the chamber at the prescribed level. Thereafter, the inside of the chamber is purged with an inert gas for a prescribed time period, after which the chamber is cooled to ambient temperature and the dry crack-free porous gel is removed. The resulting dry gels are crack-free and monolithic.

Title: Regenerative desiccant air dryer
Inventor: MITSCH MATTHEW D
IPC: B60T17/00
Filed: 1997-04-22
Abstract: A gas drying canister housing for a desiccant canister in a gas dryer system includes a main portion having an upper base and a lower portion having a lower base.  A canister bore is defined between the upper and lower bases when the main and lower portions are fastened to each other.  The main portion defines a supply port through which a stream of moisture-bearing gas is directed into the housing for passage through the desiccant canister during a drying mode of operation of the gas dryer system.  The main portion also defines a delivery port through which a stream of dried gas is directed from the housing during the drying mode.  The lower portion defines a purge port through the lower base through which a stream of remoisturized gas is expelled from the housing during a purge mode of operation of the gas dryer system.  The upper base of the main portion features a sealing flange against which an outer rim portion of a top of the desiccant canister is seatable so as to make an air tight seal therebetween.   The gas drying canister housing further includes a mechanism for aligning and securably retaining the desiccant  canister  within  the  housing  such  that  when  the desiccant canister is so aligned and securably retained the top of the desiccant canister aligns with and seals against the sealing flange and communication between the supply and delivery ports of the housing is possible only through the desiccant canister.
